Description

Technical Field

[0001] This application relates to the field of vehicle control technology, and in particular to a range extender control method, device, electronic device and storage medium. Background Technology

[0002] With the continuous advancement of technology, vehicles are becoming increasingly intelligent, and new energy vehicles have become the focus of the market. Among them, new energy vehicles equipped with range extenders can replenish the power battery through the range extender, thereby extending the vehicle's driving range to a certain extent.

[0003] However, current technologies for controlling range extenders primarily focus on the experience of occupants, such as smooth power delivery and noise control, without considering the sensory experience of pedestrians around the vehicle. This limitation could lead to noise, vibration, or exhaust emissions generated during range extender operation negatively impacting pedestrians, thereby reducing their comfort and acceptance of the vehicle. Summary of the Invention

[0004] In view of this, embodiments of this application provide a range extender control method, apparatus, electronic device, and storage medium to solve the problem in the related art that the sensory experience of pedestrians around the vehicle is not considered when controlling the range extender, resulting in adverse effects on pedestrians.

[0005] A first aspect of this application provides a range extender control method, the method comprising: upon detecting a target object, determining distance information between the target object and a vehicle; if the distance information between the target object and the vehicle is lower than a preset first distance threshold, acquiring the remaining charge of the vehicle's power battery; determining a target fuel-electricity replenishment power of the vehicle based on the remaining charge of the power battery and the vehicle's power demand, the target fuel-electricity replenishment power being the fuel-electricity replenishment power required to meet the power demand; and controlling the vehicle's range extender based on the target fuel-electricity replenishment power.

[0006] A second aspect of this application provides a range extender control device, comprising: a detection module for determining distance information between a target object and a vehicle when a target object is detected; a power module for acquiring the remaining power of the vehicle's power battery if the distance information between the target object and the vehicle is lower than a preset first distance threshold; a power module for determining a target fuel-electricity replenishment power of the vehicle based on the remaining power of the power battery and the vehicle's power demand, wherein the target fuel-electricity replenishment power is the fuel-electricity replenishment power required to meet the power demand; and a control module for controlling the vehicle's range extender based on the target fuel-electricity replenishment power.

[0007] A third aspect of this application provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the above-described method.

[0008] A fourth aspect of this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the above-described method.

[0009] The beneficial effects of this application embodiment compared with the prior art are as follows: When a target object is detected, the method in this application embodiment determines the distance information between the target object and the vehicle; if the distance information between the target object and the vehicle is lower than a preset first distance threshold, the remaining power of the vehicle's power battery is obtained; based on the remaining power of the power battery and the vehicle's power demand, the target fuel replenishment power of the vehicle is determined; the vehicle's range extender is controlled according to the target fuel replenishment power. When the target object approaches the vehicle, this application determines the target fuel replenishment power required to maintain the power demand based on the remaining power of the vehicle's power battery and the vehicle's power demand, and then controls the vehicle's range extender according to the target fuel replenishment power, avoiding the range extender from operating at a large fuel replenishment power. This allows the range extender to maintain the vehicle's power demand while minimizing the impact of noise, heat damage, and emissions, avoiding the problem in related technologies where the sensory experience of pedestrians around the vehicle is not considered when controlling the range extender, resulting in adverse effects on pedestrians.

[0023] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0024] A range extender control method and apparatus according to embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0025] This application provides a range extender control method. Figure 1 This application provides a range extender control method, such as... Figure 1 As shown, the method includes:

[0026] S101. If a target object is detected, determine the distance information between the target object and the vehicle;

[0027] S102. If the distance between the target object and the vehicle is lower than a preset first distance threshold, then obtain the remaining power of the vehicle's power battery.

[0028] S103. Based on the remaining power of the power battery and the vehicle's power demand, determine the target fuel replenishment power of the vehicle. The target fuel replenishment power is the fuel replenishment power required to meet the power demand.

[0029] S104. Control the vehicle's range extender according to the target fuel replenishment power.

[0030] It is understood that the range extender control method provided in this example is applied to vehicles equipped with range extenders. These vehicles include vehicles with autonomous or intelligent driving capabilities (including passenger vehicles (such as cars, buses, coaches, minibuses, etc.), cargo vehicles (such as ordinary trucks, box trucks, trailer trucks, enclosed trucks, tank trucks, flatbed trucks, container trucks, dump trucks, special structure trucks), special vehicles (such as logistics delivery vehicles, automated guided vehicles (AGVs), patrol vehicles, cranes, excavators, bulldozers, loaders, road rollers, off-road engineering vehicles, armored engineering vehicles, sewage treatment vehicles, sanitation vehicles, vacuum trucks, floor scrubbers, water sprinkler trucks, sweeping robots, food delivery robots, shopping guide robots, lawnmowers, golf carts, etc.), recreational vehicles (such as amusement vehicles, amusement park autonomous driving devices, balance bikes, etc.), and rescue vehicles (such as fire trucks, ambulances, power repair vehicles, engineering emergency vehicles, etc.)).

[0031] like Figure 2 As shown, Figure 2 The diagram shown is a basic structural schematic of the aforementioned vehicle, which includes:

[0032] 1. Millimeter-wave radar: Utilizing beamforming technology, it can accurately calculate the distance between the target and the vehicle by analyzing the radar signals reflected back from the target, and can track multiple targets simultaneously. The millimeter-wave radar transmits the collected distance and number of targets to the intelligent driving domain controller.

[0033] 2. Camera: It takes pictures and learns the typical features of the target object and uses image processing technology to identify some typical target objects, such as: adult target objects, child target objects, cyclist target objects, etc.

[0034] 3. Autonomous Driving Controller (ADC): Data processing and control module. It receives information from millimeter-wave radar regarding the distance and number of target objects (or other targets) relative to the vehicle. After processing the data, if the trigger condition is met—that is, the presence of any target object within the vehicle's first distance threshold—the ADC sends a pedestrian proximity warning signal to the vehicle controller via the gateway. If the pedestrian proximity warning deactivation condition is met—that is, the absence of any target object within the vehicle's second distance threshold—the ADC deactivates the pedestrian proximity warning.

[0035] 4. Vehicle Domain Controller (VDC): If the VDC receives a pedestrian proximity warning signal from the ADC, it will limit the fuel-electric power (reducing the fuel-electric power, but still meeting the minimum fuel-electric power requirements; the specific limiting method will be explained in detail later) and request the engine management system to adjust the range extender's power to the target fuel-electric power. After the VDC has limited the range extender's fuel-electric power, if the VDC receives a message from the ADC to cancel the pedestrian proximity warning, the VDC will wait for a time interval Ts (calibrated value) to determine if the pedestrian proximity warning will be triggered again: ① If it is triggered again within Ts (calibrated value), the VDC will maintain the fuel-electric power limitation action; ② If it is not triggered after Ts (calibrated value) timeout, the VDC will cancel the fuel-electric power limitation action and request the engine management system to restore the range extender's fuel-electric power to its original operating level.

[0036] 5. Engine Management System (EMS): The EMS receives requests from the VDC to reduce / restore fuel charging power and controls the range extender's fuel charging power to decrease / increase.

[0037] 6. Battery Management System (BMS): The BMS uses the power sensor to feed back the SOC information of the power battery to the vehicle controller (VDC), and receives the high voltage request from the vehicle controller (VDC) to execute the high voltage connection of the power battery. It can also replenish the low voltage battery.

[0038] 7. Gateway (GW): The role of the gateway (GW) is to convert and transmit data between different networks, and to be responsible for the signal interaction between the Intelligent Driving Domain Controller (ADC), the Vehicle Controller (VDC), and the Engine Management System (EMS).

[0039] It is understandable that vehicles can use cameras to detect the environment around them to determine if there are any target objects. If a target object is detected, the distance between the target object and the vehicle can be determined by sensors such as cameras and millimeter-wave radar. These target objects include, but are not limited to, pedestrians (adults and children) and cyclists (motorcycle riders, bicycle riders, and electric scooter riders).

[0040] This example does not limit the types of cameras mentioned above. For example, the types of cameras mentioned above include, but are not limited to, surround view cameras, night vision cameras, infrared or thermal imaging cameras, etc.

[0041] In some examples, after determining the distance information between the target object and the vehicle, this application will also compare the distance information between the target object and the vehicle with a preset first distance threshold. If the distance information between the target object and the vehicle is higher than or equal to the preset first distance threshold, it indicates that the target object and the vehicle are far apart, and the operation of the range extender will not affect the target object. Therefore, this application will stop the subsequent process until the distance information between the target object and the vehicle is lower than the preset first distance threshold. If the distance information between the target object and the vehicle is lower than the preset first distance threshold, it indicates that the target object and the vehicle are close together, and the operation of the range extender will affect the target object. In this case, this application will obtain the remaining power of the vehicle's power battery.

[0042] In some examples, this application also determines the target fuel-electricity replenishment power of the vehicle based on the remaining charge of the power battery and the vehicle's power demand. The target fuel-electricity replenishment power is the fuel-electricity replenishment power required to meet the power demand. Specifically, when the vehicle replenishes the power battery through the range extender, if the distance information between the target object and the vehicle is lower than a first distance threshold, it indicates that the target object is relatively close to the vehicle. If the range extender operates at a higher fuel-electricity replenishment power at this time, it will cause the target object to experience greater noise, heat, and emissions from the range extender, thereby affecting pedestrians' perception of the vehicle. To avoid this problem... This application considers the remaining charge of the power battery and the vehicle's power demand. The power demand represents the power required for the vehicle's current driving, and the remaining charge of the power battery represents the power that the power battery can provide. Based on the power demand and the remaining charge of the power battery, the target fuel replenishment power of the vehicle is determined. The target fuel replenishment power is the fuel replenishment power required to meet the power demand. That is, the target fuel replenishment power is the minimum fuel replenishment power of the range extender. When the range extender replenishes the power battery with the target fuel replenishment power, it can maintain the vehicle's power demand and will not cause the vehicle's power to be limited.

[0043] Subsequently, this application controls the vehicle's range extender based on the target fuel-electricity replenishment power, so that the range extender can maintain the vehicle's power demand while minimizing the impact of noise, heat damage, and emissions.

[0044] According to the technical solution provided in the embodiments of this application, when a target object is detected, the distance information between the target object and the vehicle is determined; if the distance information between the target object and the vehicle is lower than a preset first distance threshold, the remaining power of the vehicle's power battery is obtained; based on the remaining power of the power battery and the vehicle's power demand, the target fuel replenishment power of the vehicle is determined; the vehicle's range extender is controlled based on the target fuel replenishment power. In this application, when a target object approaches the vehicle, the target fuel replenishment power required to maintain the power demand is determined based on the remaining power of the vehicle's power battery and the vehicle's power demand. Subsequently, the vehicle's range extender is controlled based on the target fuel replenishment power to avoid the range extender operating at a high fuel replenishment power. This ensures that the range extender can maintain the vehicle's power demand while minimizing the impact of noise, heat damage, and emissions. This avoids the problem in related technologies where the sensory experience of pedestrians around the vehicle is not considered when controlling the range extender, leading to adverse effects on pedestrians.

[0045] In some embodiments, such as Figure 3 As shown, based on the remaining charge of the power battery and the vehicle's power requirements, the target fuel-to-electricity charging power of the vehicle is determined, including:

[0046] S301. Determine the battery output power corresponding to the remaining power battery charge.

[0047] S302. Determine the target fuel-powered charging power based on the battery output power and power requirements.

[0048] It is understood that the aforementioned power demand refers to the power required to maintain the vehicle's normal operation. The vehicle's power demand is related to its driving mode, driving speed, and load. For example, the faster the vehicle's driving speed, the higher the power demand; the slower the vehicle's driving speed, the lower the power demand. Similarly, the higher the vehicle's load, the higher the power demand; the lower the vehicle's load, the lower the power demand. Furthermore, the power demand corresponding to the driving mode "Sport" is higher than that corresponding to the driving mode "Eco."

[0049] Specifically, this application inputs the driving mode, driving speed, and load into a pre-set power demand acquisition formula to obtain the initial power demand of the vehicle. The power demand acquisition formula is as follows:

[0050] Pinit = M × (kv·V + kl·L);

[0051] Wherein, Pinit is the initial power requirement, M is the mode coefficient corresponding to the vehicle's driving mode (different driving modes correspond to different mode coefficients, and the mode coefficient corresponding to each driving mode is flexibly set by relevant personnel according to actual needs), V is the vehicle's driving speed, kv is the weighting coefficient corresponding to the driving speed (the weighting coefficient corresponding to the driving speed is flexibly set by relevant personnel according to actual needs), L is the vehicle's load, and kl is the weighting coefficient corresponding to the load (the weighting coefficient corresponding to the load is flexibly set by relevant personnel according to actual needs).

[0052] After obtaining the initial power demand, this application will further determine the road conditions of the current driving route of the vehicle, and determine the power demand weighting coefficient based on the road conditions; for example, the power demand weighting coefficient is higher when the vehicle is driving on an uphill section compared to driving on a flat road, and the power demand weighting coefficient is higher when the vehicle is driving on a dirt road compared to driving on an asphalt road; the correspondence between different types of driving roads and power demand weighting coefficients can be flexibly set by relevant personnel according to actual needs.

[0053] After obtaining the power demand weighting coefficient and the initial power demand, this application will weight the initial power demand based on the power demand weighting coefficient to obtain the power demand.

[0054] In some examples, the initial power demand can be directly used as the power demand without needing to obtain a power demand weighting coefficient for weighting.

[0055] In some examples, this application will also determine the battery output power corresponding to the remaining power of the power battery, with different remaining power of the power battery corresponding to different battery output power; it is understood that the output power of the power battery will indeed decrease as the remaining power decreases. The correspondence between the remaining power of the power battery and the battery output power can be flexibly set by relevant personnel according to actual needs, and will not be elaborated here.

[0056] In some examples, after obtaining the battery output power and power demand, this application determines the target fuel replenishment power based on the battery output power and power demand. Specifically, this application first compares the battery output power and power demand. If the battery output power is greater than or equal to the power demand, it indicates that the remaining charge of the power battery can meet the vehicle's power demand. In this case, even if the range extender does not work, the remaining charge of the power battery can still meet the vehicle's power demand, and the target fuel replenishment power of the range extender is set to 0. If the battery output power is less than the power demand, it indicates that the remaining charge of the power battery cannot meet the vehicle's power demand. In this case, the difference between the power demand and the battery output power is used as the target fuel replenishment power.

[0057] According to the technical solution provided in the embodiments of this application, the battery output power corresponding to the remaining power of the power battery is determined; based on the battery output power and power demand, the target fuel replenishment power is determined. This application achieves accurate acquisition of the target fuel replenishment power that can meet the power demand of the vehicle.

[0058] In some embodiments, such as Figure 4 As shown, after controlling the vehicle's range extender according to the target fuel-powered battery replenishment, the method further includes:

[0059] S401. Obtain the real-time distance between the target object and the vehicle;

[0060] S402. If the real-time distance is not lower than the preset second distance threshold, the original fuel replenishment power is obtained, and the range extender is controlled according to the original fuel replenishment power. The original fuel replenishment power is the fuel replenishment power that controls the range extender before the target fuel replenishment power.

[0061] It is understandable that after controlling the vehicle's range extender according to the target fuel-electric power, this application will continue to monitor the real-time distance between the target object and the vehicle. After the target object moves away from the vehicle, the fuel-electric power of the range extender will be adjusted in a timely manner so that the range extender can operate normally according to the original fuel-electric power.

[0062] Specifically, this application will obtain the real-time distance between the target object and the vehicle; it is understood that the vehicle can obtain the real-time distance between the target object and the vehicle through devices such as cameras and millimeter-wave radar.

[0063] After obtaining the aforementioned real-time distance, this application compares the real-time distance with a pre-set second distance threshold, which is greater than the first distance threshold. If the real-time distance is not lower than the second distance threshold, it indicates that the target object has moved away from the vehicle. In this case, the vehicle's normal operation of the range extender will not affect the target object, and the vehicle obtains the original fuel-electric power and controls the range extender according to the original fuel-electric power. If the real-time distance is lower than the second distance threshold, it indicates that the target object is still near the vehicle. In this case, the vehicle's normal operation of the range extender will have an adverse effect on the target object, and the range extender is controlled according to the target fuel-electric power.

[0064] According to the technical solution provided in the embodiments of this application, the real-time distance between the target object and the vehicle is obtained; if the real-time distance is not lower than a preset second distance threshold, the original fuel replenishment power is obtained, and the range extender is controlled according to the original fuel replenishment power. This application obtains the real-time distance between the target object and the vehicle, and if the real-time distance is not lower than the second distance threshold, it determines that the normal operation of the range extender will not affect the target object. At this time, the original fuel replenishment power is obtained, and the range extender is controlled according to the original fuel replenishment power, thus ensuring the normal operation of the range extender.

[0065] In some embodiments, such as Figure 5 As shown, if the real-time distance is not lower than a preset second distance threshold, the original fuel-powered battery charge is obtained, and the range extender is controlled based on the original fuel-powered battery charge, including:

[0066] S501. If the real-time distance is not lower than the second distance threshold, then confirm the target object's distance time. The target object's distance time is the time taken for the real-time distance to be not lower than the second distance threshold.

[0067] S502. When the target object is far away for a period of time that meets the preset time threshold, obtain the original fuel replenishment power and control the range extender according to the original fuel replenishment power.

[0068] It is understandable that, in order to avoid the problem that the distance information between the target object and the vehicle changes continuously between the first distance threshold and the second distance threshold in a short period of time, which would cause the fuel replenishment power of the range extender to change continuously and affect the use of the range extender, the solution provided in this application will take the real-time distance as the situation where the target object is moving away from the vehicle when it is not lower than the second distance threshold, and then record the duration of the target object moving away from the vehicle.

[0069] When the target object is far away for a period of time that meets a preset time threshold, the original fuel-powered charging power is obtained, and the range extender is controlled according to the original fuel-powered charging power.

[0070] To better understand this application, a more specific example is provided for illustration. This application uses a camera and millimeter-wave radar to identify target objects and the distance information between the target objects and the vehicle (automobile) (camera image processing identifies the target objects, and millimeter-wave radar obtains the distance information between the target objects and the vehicle).

[0071] This application denotes the aforementioned distance information as S, such as Figure 6 As shown, the distance between the vehicle and the target object is denoted as S. If S < S1 (S1 is a preset first distance threshold), a target object proximity alert is triggered; if S ≥ S1, the target object proximity alert is not triggered. Figure 7 As shown, the system uses a camera and millimeter-wave radar to obtain information about the target object and its distance from the vehicle. (The camera image processing identifies the target object, and the millimeter-wave radar obtains the distance S between the target object and the vehicle. If S > S2 (S2 is a pre-set second distance threshold), and a pedestrian approach warning has already been triggered, then the pedestrian approach warning is deactivated. If S > S2 (calibration value), and a pedestrian approach warning has not been triggered, then the pedestrian approach warning is not triggered.)

[0072] Continuing the previous example, when a target object approaches the vehicle, i.e., if S < S1 (S1 is a pre-set first distance threshold), a target object proximity warning is triggered. The vehicle controller (VDC) will limit the range extender's fuel replenishment power (reducing the fuel replenishment power, but still meeting the minimum fuel replenishment requirement, which is the target fuel replenishment power), reducing the impact of noise, heat, and emissions generated by the range extender's fuel replenishment on the target object. The execution process is as follows: the intelligent driving domain controller (ADC) sends a target object proximity warning to the vehicle controller (VDC) through the gateway (GW). Upon receiving the target object proximity warning from the intelligent driving domain controller (ADC), the VDC sends a command to the engine management system (EMS) to reduce the generator power, causing the EMS to control the range extender according to the target fuel replenishment power. The VDC receives the execution feedback result from the EMS and sends the execution feedback back to the ADC through the gateway (GW).

[0073] If a target object approaches the vehicle and then moves away from it (i.e., S < S1 (S1 is a pre-set first distance threshold), a target object proximity warning is triggered. If S > S2, the target object proximity warning is deactivated. If the target object approaches and then moves away from the vehicle, S > S2 (calibrated value), the target object proximity warning is deactivated, and the vehicle controller (VDC) releases the restriction and restores the range extender's fuel replenishment power or continues to restrict the range extender's fuel replenishment power. The specific strategy is as follows: The intelligent driving domain controller (ADC) sends a message to the vehicle controller (VDC) to deactivate the target object proximity warning via the gateway (GW); the vehicle controller (VDC) receives the message from the intelligent driving domain controller... The ADC sends a notification to cancel the target object proximity alert. The VDC maintains the fuel replenishment power limit of the range extender based on the target fuel replenishment power and waits for Ts (a pre-set time threshold) to determine whether the target object proximity alert will be triggered again. If the target object proximity alert is triggered again within Ts (calibration value), the VDC maintains the fuel replenishment power limit. If the target object proximity alert is not triggered within Ts (calibration value), the VDC cancels the fuel replenishment power limit and requests the EMS to restore the original fuel replenishment power level. The VDC receives the execution feedback result from the EMS and sends the execution feedback to the ADC through the gateway GW.

[0074] When a target object proximity warning is triggered, this application limits the fuel replenishment power of the range extender by the vehicle controller (VDC) (controlling the range extender according to the target fuel replenishment power to meet the minimum fuel replenishment requirements corresponding to the vehicle's power demand). This avoids the target object near the vehicle experiencing the impact of the range extender's high fuel replenishment power on the target object due to the high fuel replenishment power of the range extender. It optimizes the impact of the range extender's fuel replenishment on the target object in a more humane and intelligent way, making the range-extended vehicle more friendly to the vehicle's surrounding environment or target objects, and increasing market favorability and acceptance of the product.

[0075] According to the technical solution provided in the embodiments of this application, when the real-time distance is not lower than the second distance threshold, the distance time of the target object is confirmed. When the distance time of the target object meets the preset time threshold, the original fuel replenishment power is obtained, and the range extender is controlled according to the original fuel replenishment power. This application avoids the problem that the distance information between the target object and the vehicle changes continuously between the first distance threshold and the second distance threshold in a short period of time, which would cause the fuel replenishment power of the range extender to change continuously and affect the use of the range extender, while controlling the normal operation of the range extender in a timely manner.

[0076] In some embodiments, such as Figure 8 As shown, when a target object is detected, the distance information between the target object and the vehicle is determined, including:

[0077] S801. Acquire image information about the area surrounding the vehicle and perform object recognition on the image information;

[0078] S802. If the object recognition result indicates the existence of a target object, then determine the distance information between the target object and the vehicle.

[0079] It is understood that this application acquires image information about the vehicle's surroundings through a camera, and then performs object recognition on the image information. If the object recognition result indicates that there is a target object around the vehicle, the distance information between the target object and the vehicle is determined; if the object recognition result indicates that there is no target object around the vehicle, the distance information between other targets and the vehicle will not be determined, thereby avoiding the problem of invalid acquisition of distance information.

[0080] It is understood that if the image information contains multiple other targets but no target object exists, this application will not determine the distance information between the other target objects and the vehicle. If the image information contains multiple target objects, this application will obtain the distance information between each target object and the vehicle, and take the shortest distance information as the distance information between the target object and the vehicle.

[0081] According to the technical solution provided in the embodiments of this application, this application acquires image information around the vehicle through a camera, and then performs object recognition on the image information. If the object recognition result indicates that there is a target object around the vehicle, the distance information between the target object and the vehicle is determined; if the object recognition result indicates that there is no target object around the vehicle, the distance information between other targets and the vehicle will not be determined, thus avoiding the problem of invalid acquisition of distance information and improving the efficiency of system resource utilization.

[0082] In some embodiments, such as Figure 9 As shown, the range extender that controls the vehicle's fuel-powered charging capacity according to the target fuel replenishment power includes:

[0083] S901. Obtain the pre-set standard fuel replenishment power, which is the fuel replenishment power set according to the operating characteristics of the range extender.

[0084] S902. If the target fuel-powered battery is greater than the standard fuel-powered battery, the range extender will be controlled to operate at the target fuel-powered battery.

[0085] S903. If the target fuel-powered battery is less than the standard fuel-powered battery, the range extender will be controlled to operate at the standard fuel-powered battery.

[0086] It is understood that this application will also pre-set a standard fuel replenishment power, which is a fuel replenishment power set according to the operating characteristics of the range extender. When the range extender operates at this standard fuel replenishment power, it will not have an adverse effect on the target object within the first distance threshold.

[0087] This application compares the target fuel-powered battery replenishment power with the standard fuel-powered battery replenishment power. If the target fuel-powered battery replenishment power is greater than the standard fuel-powered battery replenishment power, the range extender will be controlled to operate at the target fuel-powered battery replenishment power, thereby maximizing the range extender's ability to replenish the power battery.

[0088] If the target fuel-powered charging power is less than the standard fuel-powered charging power, the range extender will be controlled to operate at the target fuel-powered charging power, thereby minimizing the impact of the range extender on the target object during operation.

[0089] If the target fuel-powered electric charge is equal to the standard fuel-powered electric charge, then the range extender is controlled to operate at either the target fuel-powered electric charge or the standard fuel-powered electric charge.

[0090] According to the technical solution provided in the embodiments of this application, a pre-set standard fuel replenishment power is obtained. The standard fuel replenishment power is the fuel replenishment power set according to the operating characteristics of the range extender. If the target fuel replenishment power is greater than the standard fuel replenishment power, the range extender is controlled to operate at the target fuel replenishment power. If the target fuel replenishment power is less than the standard fuel replenishment power, the range extender is controlled to operate at the standard fuel replenishment power.

[0091] In some embodiments, such as Figure 10 As shown, after controlling the vehicle's range extender according to the target fuel-powered battery replenishment, the method further includes:

[0092] S1001. If the vehicle's power requirements are updated, the target fuel-to-electricity power of the vehicle shall be redefined.

[0093] S1002. Control the range extender according to the redefined target fuel replenishment power.

[0094] It is understandable that a vehicle's power demand is not static. As described in steps S301 and S302, a vehicle's power demand is related to parameters such as the vehicle's driving mode, driving speed, and load. When the vehicle's driving mode, driving speed, or load changes, the vehicle's power demand changes accordingly.

[0095] Based on the above principle, when the vehicle's power demand is updated, this application will redetermine the vehicle's target fuel-electric power supply, so that the redetermined target fuel-electric power supply can meet the vehicle's power demand, and then control the range extender according to the redetermined target fuel-electric power supply.

[0096] For example, at the first moment, the vehicle speed is 10 km / h, and the vehicle's power demand is determined to be A. The target fuel-electric power corresponding to this power demand is X. That is, when the range extender operates at the target fuel-electric power of X, the power of the vehicle's battery and the range extender can meet the vehicle's power demand. At the second moment, under the condition that other factors remain unchanged, the vehicle speed is 20 km / h, and the vehicle's power demand is determined to be B. Power demand B is greater than power demand A. At this time, if the range extender is still controlled to operate at the target fuel-electric power of X, the power of the vehicle's battery and the range extender cannot meet the vehicle's power demand. Therefore, when the vehicle's power demand is updated, this application will re-determine the target fuel-electric power corresponding to power demand B. If the target fuel-electric power corresponding to power demand B is Y (that is, when the range extender operates at the target fuel-electric power of X, the power of the vehicle's battery and the range extender can meet the vehicle's power demand), then the range extender will be controlled according to the re-determined target fuel-electric power Y.

[0097] According to the technical solution provided in the embodiments of this application, if the vehicle's power demand is updated, the target fuel-electricity replenishment power of the vehicle is re-determined; the range extender is controlled according to the re-determined target fuel-electricity replenishment power, so that the range extender can still meet the vehicle's power demand after the vehicle's power demand is updated, thereby improving the user experience.

[0098] All of the above-mentioned optional technical solutions can be combined in any way to form the optional embodiments of this application, and will not be described in detail here.

[0099] The following are embodiments of the apparatus described in this application, which can be used to execute the embodiments of the method described in this application. For details not disclosed in the apparatus embodiments of this application, please refer to the embodiments of the method described in this application.

[0100] This embodiment also provides a range extender control device, such as... Figure 11 As shown, the device includes:

[0101] The detection module 1101 is used to determine the distance information between the target object and the vehicle when the target object is detected.

[0102] The power module 1102 is used to obtain the remaining power of the vehicle's power battery if the distance between the target object and the vehicle is lower than a preset first distance threshold.

[0103] The power module 1103 is used to determine the target fuel replenishment power of the vehicle based on the remaining power of the power battery and the power demand of the vehicle. The target fuel replenishment power is the fuel replenishment power required to meet the power demand.

[0104] Control module 1104 is used to control the vehicle's range extender according to the target fuel replenishment power.

[0105] In some examples, the power module 1103 is also used to determine the battery output power corresponding to the remaining charge of the power battery; and to determine the target fuel replenishment power based on the battery output power and power demand.

[0106] In some examples, the control module 1104 is also used to obtain the real-time distance between the target object and the vehicle; if the real-time distance is not lower than a preset second distance threshold, the original fuel replenishment power is obtained, and the range extender is controlled according to the original fuel replenishment power, wherein the original fuel replenishment power is the fuel replenishment power used to control the range extender before the target fuel replenishment power.

[0107] In some examples, the control module 1104 is also used to confirm the distance-away time of the target object if the real-time distance is not lower than the second distance threshold, wherein the distance-away time of the target object is the timing duration when the real-time distance is not lower than the second distance threshold; when the distance-away time of the target object meets the preset duration threshold, the original fuel replenishment power is obtained, and the range extender is controlled according to the original fuel replenishment power.

[0108] In some examples, the detection module 1101 is also used to acquire image information around the vehicle and perform object recognition on the image information; if the object recognition result indicates the existence of a target object, then the distance information between the target object and the vehicle is determined.

[0109] In some examples, the control module 1104 is also used to obtain a pre-set standard fuel replenishment power, which is a fuel replenishment power set according to the operating characteristics of the range extender; if the target fuel replenishment power is greater than the standard fuel replenishment power, the range extender is controlled to operate at the target fuel replenishment power; if the target fuel replenishment power is less than the standard fuel replenishment power, the range extender is controlled to operate at the standard fuel replenishment power.

[0110] In some examples, the control module 1104 is also used to redetermine the target fuel-electric power of the vehicle in the event of an update in the vehicle's power demand; and to control the range extender based on the redetermined target fuel-electric power.

[0111] According to the technical solution provided in this application embodiment, the range extender control device provided in this embodiment determines the distance information between the target object and the vehicle when a target object is detected; if the distance information between the target object and the vehicle is lower than a preset first distance threshold, the remaining power of the vehicle's power battery is obtained; based on the remaining power of the power battery and the vehicle's power demand, the target fuel replenishment power of the vehicle is determined; and the vehicle's range extender is controlled according to the target fuel replenishment power. This application determines the target fuel replenishment power required to maintain power demand based on the remaining power of the vehicle's power battery and the vehicle's power demand when the target object approaches the vehicle. Subsequently, the vehicle's range extender is controlled according to the target fuel replenishment power, avoiding the range extender from operating at a high fuel replenishment power. This ensures that the range extender can maintain the vehicle's power demand while minimizing the impact of noise, heat damage, and emissions, avoiding the problem in related technologies where the sensory experience of pedestrians around the vehicle is not considered when controlling the range extender, leading to adverse effects on pedestrians.
